I suggest the following entry in your /etc/make.conf, since this
workaround is not practicable if the ports tree is shared read only.

WRKDIRPREFIX?= /space/portbuild

This way you have some benefits.
 - you can mount the portstree read only
 - defined space for building and cleanup (not in the directory of the port)
 - quick cleanup with rm -rf /space/portbuild
 - you can mount a ramdisk or tmpfs to the directory
   ( mount -t tmpfs tmpfs /space/portbuild)
